摘要翻译:
鱼类捕食会影响两栖动物种群。大多数例子报告了入侵鱼类物种及其对特定两栖动物的负面影响。在这里,我们提供了一个自然的鱼类捕食热带gar阿tractosteus tropicus对甘蔗蟾蜍Bufo marinus。我们观察到热带吸虫攻击海洋吸虫造成的物理损害。当成年蟾蜍从种群中移除时,亚成体蟾蜍重新进入成虫生态位,重新补充种群。鱼类捕食两栖动物的局部观察对区分自然种群波动和两栖动物种群下降很重要。

英文摘要:
Fish predation can affect amphibian populations. Most examples report invasive fish species and their negative effect on specific amphibians. Here we provide an occurrence of natural fish predation by the tropical gar Atractosteus tropicus on the cane toad Bufo marinus. We observed physical damage caused by A. tropicus attacking B. marinus. When adult B. marinus were removed from the population subadult toads refilled the adults niche, resupplementing the population. Local observations of predation by fish on amphibians are important to differentiate natural population fluctuations from amphibian population declines.
